What could be a more quinessential New England sports moment than “The Green Monsters” of the NBA attacking the Green Monster?

“A fun day, beautiful day in Fenway, a dream come true … I felt like I was 10 years old,” Celtics general manager Danny Ainge told the Boston Herald.

It’s understandable that Ainge enjoyed returning to his roots, considering his previous career in baseball with the Toronto Blue Jays.

But it was also fun for Boston forward Paul Pierce.

“That was one of the best days of my life, actually, man,” Pierce said. “You had to be there to know what I’m talking about.”

And it continues a trend for the Celtics, who have shared some unique team-bonding activities over the last few years. They dressed up in Roman garb during a visit to the Coliseum last year. There have been trips to check out Doc Rivers’ house, where they checked out his new duck boat. Later that day, they watched an advance screening of the movie “Due Date.”

“We sure as hell didn’t do it in Minnesota,” Boston forward Kevin Garnett said. “I haven’t heard about anything else in the league, nor do I care. We’re having a blast, man. We come in here and bust each others’ (butts), we go at each other pretty hard. And off the court we relax and try to get to know each other.”

Gregg Popovich talked about a trip to Gonzales on Saturday afternoon to sample some lamb ribs as a way to get away from the tedium of training camp.

But I wouldn’t expect a veteran squad like the Spurs to get together very often in their rare time away from basketball. Popovich’s intense practices provide all of the bonding they’ll need for the next few weeks.
